Central waste water treatment plant of Ljubljana

The central waste water treatment plant of Ljubljana  (Ljubljana CWWTP) is a single-stage mechanical and biological treatment plant intended for the removal of undissolved substances and carbon compounds, and nitrification. The treatment of the excess sludge produced in this process involves anaerobic stabilisation of sludge in heated digesters and machine condensation and the drying of sludge to the point where the content of dry substance is above 90%. Owing to appropriate processing, dried excess sludge is a useful waste. The biogas produced in the anaerobic process is used in the sludge drying and digester heating process.
